English uses it in two slightly different shapes, and mixing them up is the usual student error. Uncountable, with no article or with 'the': 'unfairness in the workplace', 'the unfairness of it all'. This is the normal use — unfairness as a quality spread through a situation. Countable, in the plural: 'the small unfairnesses of daily life' — separate individual unfair things.

English uses it in two slightly different shapes英文有兩種稍微不同的用法， and mixing them up is the usual student error學生最常犯的錯就是把它們搞混。Uncountable不可數用法， with no article or with 'the'前面不加冠詞或加「the」： 'unfairness in the workplace'「unfairness in the workplace（職場上的不公）」、 'the unfairness of it all'「the unfairness of it all（這一切的不公）」。This is the normal use這是正常的用法 — unfairness as a quality spread through a situation把unfairness當成瀰漫在情況裡的一種性質。Countable可數用法， in the plural用複數： 'the small unfairnesses of daily life'「the small unfairnesses of daily life（日常生活中一件件小小的不公）」 — separate individual unfair things指個別、單獨的不公平事件。

That plural is rarer and a bit literary. You will meet it most in serious writing about work, school, law, money, and society: 'a deep sense of unfairness', 'to complain about the unfairness of the rules', 'perceived unfairness' (people feel it is unfair, whether or not it is).

That plural這種複數用法 is rarer比較少見 and a bit literary也偏書面。You will meet it most in serious writing about work, school, law, money, and society你最常在談工作、學校、法律、金錢和社會議題的嚴肅文章裡遇到它： 'a deep sense of unfairness'「a deep sense of unfairness（深深的不公平感）」、 'to complain about the unfairness of the rules'「to complain about the unfairness of the rules（抱怨規則不公平）」、 'perceived unfairness'「perceived unfairness（感受到的不公平）」 (people feel it is unfair, whether or not it is)（不管是否真的不公平）。

Notice 'a sense of unfairness' — that fixed phrase is how English usually talks about the experience of being treated badly, and it is very common in news and social writing. In ordinary speech, though, people rarely reach for the noun. They say 'that's not fair' or 'it's so unfair'. The noun belongs to writing, to arguments, to essays — which, for a student taking exams, is exactly where you need it.
